B4J Question Changing the Y-origin of a text

[wimpie3]

When using canvas.DrawText to draw text on a B4XCanvas, it seems the Y coordinate is the BOTTOM of the text, the baseline.

How can I use the TOP as the Y coordinate?

According to https://docs.oracle.com/cd/E17802_0...javafx.scene.text/javafx.scene.text.Text.html there seems to be an option called "textOrigin", but that parameter isn't available in B4XCanvas. How can I do this?

I get strange values like 3.1999998 for the width or height. I thought that on Java pixels were used as units. Am I wrong?

Also, for pixel precise measurement on fonts with symbols, the anti aliasing seems to be taken into account with the measurement. Hence my other question if it's possible to disable the anti aliasing to get a pixel perfect measurement.
